NEW YORK -- New York Mayor Michael Bloomberg's aides are getting creative about trying to keep his parked SUVs cool in hot weather.

The New York Post reports that workers put a room air conditioner in a window of one of his SUVs to see if it would fit.

If approved, the AC would be plugged into electrical outlets, creating less pollution than an idling vehicle.

Mayoral spokesman Stu Loeser said it was an experiment to be used on extremely hot days. He said even with the vehicles parked in the shade, the temperatures inside can rise to more than 100 degrees. The SUVs carry communications equipment that can get overheated.

In 2009, Bloomberg apologized for letting his parked SUVs idle and stopped the practice.
